The Names??

Rating: 9/10 (12 October 2015)

An excellent movie. Vastly underrated. A lot of action movies dedicate the plot to hot women and big guns. This movie was not like that. It had the perfect combination of Drama, Action, and Romance (and even as a guy, I can appreciate it when it's not blown out of proportion, like in CF's). However, I'm a little confused about the names of the clones in the movie. We find out that the final titles in their names mean how old they are (Echo:3 Delta:4; etc.) And, the first titles we later figure out are the last names of their sponsors (people who had them made). But we are never told what the numbers in the middle mean (or maybe I missed it). Lincoln "6" Echo, Jordan "2" Delta..? I think it means what number they are in their generation off the assembly line (so to speak), but I'm not sure. Anyone have any ideas??
